Porygon

Taking small LCD screens, a tiny computer running Linux, and a 3D printed enclosure to build miniature versions of old computers is a thing now. Here’s [Cupcakus]’s tiny little Apple II, complete with Oregon Trail. This Apple II is running on a C.H.I.P., uses a 3s lithium battery from a drone, and works with a Bluetooth keyboard and joystick. Yes, the power button on the monitor works.

At Hackaday, we get a lot of emails from people asking the most important question ever: “how do you become a hardware hacker?” [Tex Projects] lays it all out on the line. All you need to do is to buy five of something every time you need one. Need some header pins? Buy five. A sensor? five. Come to the realization that anything you build could be bought for less money.

Are we still doing low-poly Pokemon? [davedarko] has an idea for the Sci-Fi contest we’re running. He’s going to give children seizures. He’s refreshing a project of mine by putting lights, blinkies, and noisy things in a 3D printed Porygon, the original 3D printed Pokemon. Porygon was the subject of that one episode of the Pokemon cartoon that sent 635 Japanese children to the hospital. The episode was banned in America, but it was actually Pikachu that caused the flashing lights.

‘Member Clickspring? He’s the guy who made a fantastic mechanical clock using nothing except a few bits of brass, a blowtorch, a tiny mill and lathe, and a lot of patience. Now he’s building the Antikythera mechanism. The Antikythera mechanism is a 2000-year-old device designed to calculate the phases of the moon, the motion of the planets, and other local astronomical phenomena. This is going to be a masterpiece, and will eventually end up in a museum, so be sure to subscribe to his YouTube channel.

[TJ Hunter] wanted to find some of the rarer Pokémon without draining his smartphone battery while staring on a screen. The handy ø 25 cm Pokéball he built to make the endless marches more tolerable detects nearby Pokémon and wiggles to alert its owner if there’s a rare catch in sight.

Misumi is doing something pretty interesting with their huge catalog of aluminum extrusions, rods, bolts, and nuts. They’re putting up BOMs for 3D printers. If you’ve ever built a printer with instructions you’ve somehow found on the RepRap wiki, you know how much of a pain it is to go through McMaster or Misumi to find the right parts. Right now they have three builds, one with linear guides, one with a linear shaft, and one with V-wheels.

So you’re finally looking at those fancy SLA or powder printers. If you’re printing an objet d’arte like the Stanford bunny or the Utah teapot and don’t want to waste material, you’re obviously going to print a thin shell of material. That thin shell isn’t very strong, so how do you infill it? Spheres, of course. By importing an object into Meshmixer, you can build a 3D honeycomb inside a printed object. Just be sure to put a hole in the bottom to let the extra resin or powder out.

Remember that episode of The Simpsons where Homer invented an automatic hammer? It’s been reinvented using a custom aluminum linkage, a freaking huge battery, and a solenoid. Next up is the makeup shotgun, and a reclining toilet.

[Jan] built a digitally controlled analog synth. We’ve seen a few of his FM synths VA synths built from an LPC-810 ARM chip before, but this is the first one that could reasonably be called an analog synth. He’s using a digital filter based on the Cypress PSoC-4.

The hip thing to do with 3D printers is low-poly Pokemon. I don’t know how it started, it’s just what the kids are doing these days. Those of us who were around for Gen 1 the first time it was released should notice a huge oversight by the entire 3D printing and Pokemon communities when it comes to low-poly Pokemon. I have corrected this oversight. I’ll work on a pure OpenSCAD model (thus ‘made completely out of programming code’) when I’m sufficiently bored.
